The minutes were approved as presented.
4. CHAIR’S REPORT
Grant Crosby replaces Steve Peterson as the principal representative from the US Department of
the Interior, and Todd Neitzel continues to serve as the alternate representative.
Steve Rocklin, formerly representing State of New York Department of State, is appointed as
alternate to Nick Artim representing T.Y. Lin International.
Don thanked Shelia Palmer for taking over for Steve Peterson as the task group chair for NFPA
914 – Code for Fire Protection of Historic Structures.
Don asked for volunteers to serve on the 909 task group and the following members volunteered:
Debbie Freeland, Wilbur Faulk, Dan Hubert, Tom Norton, Fred Leber, Scott Franson and Cindy
Greczek. Cindy said Danny McDaniel would also like to serve on the task group.
Don thanked Cindy Greczek for volunteering to fill in as committee secretary since Mike Coull
was unable to attend the meeting.
5. STAFF LIAISON’S REPORT
Greg Harrington conducted a training session and provided a booklet on the new NFPA
standards development process, which included changes in terminology, process for requesting
assistance from the Fire Protection Research Foundation, navigating the document info page and
casting electronic ballots. Committee members are encouraged to familiarize themselves with the
new regulations. Complete details on the new process are available at the NFPA website:
http://www.nfpa.org/categoryList.asp?categoryID=164
6. REVIEW SCHEDULE FOR FUTURE COMMITTEE MEETINGS
September 24-25, 2013 (NFPA 914 Pre Second Draft Meeting). Tom Norton confirmed the
meeting location will be the Maine Maritime Museum in Bath, Maine and will also include a tour of
the Bath Shipyard.
April 28 – May 2, 2014 (NFPA 914 Second Draft Meeting). Fred Leber said he can arrange for a
meeting facility in Kona Hawaii.
CUL-AAA FIRST DRAFT MEETING MINUTES - APRIL 23-24, 2013 Page 2 of 5Page 7 of 12
Fall 2014 (NFPA 909 Pre-First Draft Meeting). The committee will ask Todd Neitzel to look into a
meeting facility at Yellowstone or Grand Canyon National Park.
Spring 2015 (NFPA 909 First Draft Meeting). Debbie Freeland suggested polling the committee
members to identify future meeting facilities/locations.
7. NFPA 914 TASK GROUP REPORT
Shelia Palmer, who replaced Steve Peterson as task group chair, provided an overview of the
task group’s work as follows: a new section on security, new annex material on historic districts,
updates to reference documents and overall clarifying of language. Shelia presented the
revisions made to Chapters 1 through 15 and Ray Allshouse presented the revisions made to
Annex S. Ray added that the greatest risk to a historic district is fire, guidance is needed on how
to set up a historic district and fire planning will follow.
The committee reviewed the public input and created numerous First Revisions on NFPA 914.
See the First Draft Report on the NFPA 914 document information page (www.nfpa.org/914) for
the final actions. Shelia also provided copies of the Secretary of the Interior’s Standards for the
Treatment of Historic Properties to all committee members.
8. PORTABLE FIRE EXTINGUISHER AGENT TASK GROUP REPORT
Cindy Greczek confirmed that the Colonial Williamsburg Foundation submitted the grant
application to the Institute for Museum and Library Services (IMLS) in January 2013 and received
confirmation from IMLS the grant application was received and is being evaluated. An award
decision from IMLS is expected fall of 2013. Cindy also said Colonial Williamsburg
archaeological conservator Emily Williams is working on a paper to present at an International
Council of Museums (ICOM) conference in 2014 should Colonial Williamsburg be awarded the
grant.
9. PROTECTING OUR HERITAGE UPDATE
Greg Harrington reported NFPA has a new product evaluation process and team that looked at
Protecting Our Heritage as a “for-sale” product. The team decided there is not sufficient revenue
potential considering the time, effort and expense it will take to produce this document. NFPA,
however, will support the committee in making some version of Protecting Our Heritage available.
One option might be to revise it as a white paper and post it on NFPA’s website. Greg asked for
volunteers to participate in a conference call with NFPA management to discuss this further. The
committee suggested Cheryl Domnitch and Marilyn Kaplan be involved and Shelia Palmer also
volunteered to participate. Don Moeller will follow up by discussing the issue with Cheryl. Dan
Hubert suggested the committee look for a cultural group to champion this project apart from
NFPA, for example American Association of Museums or Heritage Preservation Association.
Another committee suggestion was to add Protecting Our Heritage as an annex. All of these
ideas will be open for discussion.
10. NEW PROJECT PROPOSAL ON HYBRID GAS-FINE WATER DROPLET SYSTEMS
Don Moeller reported the Standards Council is looking for public input regarding a new standard
on this type of system. The committee discussed whether hybrid technology should be part of
CUL-AAA FIRST DRAFT MEETING MINUTES - APRIL 23-24, 2013 Page 3 of 5Page 8 of 12
NFPA 750 or a separate standard. The committee supports the need to develop a standard for
hybrid systems using a combination of inert gas and very fine water droplets, and Don will submit
a letter to the Standards Council expressing the discussions at the meeting. (See attached
memorandum to Standards Council.)
11. OTHER BUSINESS
A tour of the museum is scheduled at 1:30 pm on April 24, 2013.
12. ADJOURNMENT
The meeting was adjourned at 11:30 am on April 24, 2013.
Minutes prepared by Cindy Greczek, Acting Secretary.

Technical Committee on
Cultural Resources
M E M O R A N D U M TO: Amy Cronin, Secretary, Standards Council FROM: Don Moeller, Chair, Technical Committee on Cultural Resources DATE: April 29, 2013 SUBJ: Comment on New Standard – Hybrid Gas Fine Water Droplet Systems At its meeting on April 23, 2013, the Technical Committee on Cultural Resources voted unanimously to submit the following response to the request for public input on a new standard to address hybrid gas fine water droplet systems. I am submitting the response on the committee’s behalf. The Technical Committee on Cultural Resources supports inclusion of hybrid system technology in NFPA standards. Hybrid-type systems could potentially be used to control and/or extinguish typical hazards that are included in and considered by NFPA 909, Code for the Protection of Cultural Resource Properties – Museums, Libraries, and Places of Worship, and NFPA 914, Code for Fire Protection of Historic Structures. In addition, the committee believes that the technology should be incorporated into the current NFPA 750, Standard on Water Mist Fire Protection Systems, due to its similarity in technology in regards to both fire fighting mechanics and system component mechanics. The Technical Committee on Cultural Resources recognizes that attempts have been made to include hybrid systems under NFPA 750 and that these attempts have been rejected by the NFPA 750 technical committee. If it is the decision of the Standards Council to not incorporate hybrid system technology into NFPA 750, then we recommend and support the development of a new standard for “hybrid fire suppression systems.” Although Factory Mutual has approved hybrid systems for use in specific FM insured facilities, the lack of a national standard covering hybrid systems hampers the use of such systems even when the hybrid system provides the best option for fire extinguishment in a given hazard area. Also, lack of guidance for use of hybrid systems leaves authorities who wish to utilize hybrid technology, other than FM, without the type of definitive guidance provided by a nationally recognized consensus standard. In summary, the Technical Committee on Cultural Resources supports the inclusion of hybrid fire suppression systems technology in NFPA standards.

[909:9.12.12.3.3]
A.22.30.1.2.1 Although prior to the 2007 edition NFPA13 permitted the pipe for systems not subject to freezing to be installed without a back pitch, similar to the design of wet pipe systems, this arrangement allows water to accumulate in low points, increasing the rate of corrosion. Proper pitching is an important element in reducing the risk of corrosion. The pitch requirements included in NFPA 13 should be considered the minimum acceptable pitch. Where adequate clearance is provided to permit the system to be installed without causing interferences with structural elements or causing low points, pitches exceeding this minimum requirement such as 4mm/m(1⁄2 in. per 10 ft) should be considered. [909: A.9.12.12.3.1] A.22.30.1.2.2 Additional auxiliary drainage should be provided, in accordance with NFPA 13, regardless of whether the protected area is subject to freezing. [909: A.9.12.12.3.2.1] A.22.30.1.2.3 The wording is based on NFPA 13, 24.1.5.2. The special sensitivity of cultural resource properties to water damage that could result from piping corrosion warrants the assumption of water supplies and environmental conditions that contribute to unusual corrosive properties.
